How does the shape of the worm change as it move

Biology

In earthworms, each segment can move independently, so that alternating contractions between the two different sets of muscles in many different segments create shape changes all along the body. This produces accordion-like body movements that help the worm push through soil and maneuver through small spaces within

When the circular muscles contract, the earthworm stretches, becoming longer and thinner. The earthworm uses its setae to anchor the front of its body in the soil. Now the longitudinal muscles contract and the earthworm becomes shorter and wider or it bends from one side to the other, pulling the body forward.

If a battery produced 12.6 volts, what would the current flow be for a 6 Ohm resistor
Free_Kalibri [48]

Answer:

I = 2.1 A

Explanation:

This is physics, but I will answer here either way.

First, the battery produces a voltage of 12 V in a resistor with 6 ohm, and we want the current flow (I). We need to apply the following expression:

V = R * I   (1)

This is the Ohm's law. From here we can solve for I and:

I = V/R   (2)

Now, we just need to replace the data and solve for the current:

I = 12.6 / 6

<h2>I = 2.1 A</h2>

Hope this helps

Please help I will give BRAINLIEST face the earth
Oxana [17]

Answer:

It is often assumed that the moon is a perfect sphere, which it is not. The side of the moon facing earth is more dense than the side facing away. Therefore, it takes energy for the moon to rotate its earth-facing side away from the earth. Such energy is not currently available, so the same side always faces earth, caught in earth’s gravity.

Explanation:

Hope this helps you a lot my boo!

Gluconeogenesis shares some, but not all, enzymes with the glycolytic pathway. It would appear to be more efficient if both path
viva [34]

Answer:

D) Three of the reaction steps in gluconeogenesis would have prohibitively large, positive free energies if they used glycolytic enzymes for their catalysis.

Explanation:

The glycolytic enzymes catalyze the conversion of glucose to pyruvate, while gluconeogenesis enzymes catalyze the formation of carbohydrates from pyruvate.
